T0 at whom, it may concern:

Be it known that I, CARL J. WALLEN, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented certain new and useful Improvements in WindowConstruction; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in window construction; and itsobject is to provide a window-casing having sashes adapted when closedto fit one beneath the other.

Another object is to provide a combined guide, lock, and weather-stripwhich serves to hold the sashes securely in closed position.

A further object is to mount the lower sash in such a manner as topermit the same to be drawn from under the upper sash and raised orlowered as ordinarily, the strip before referred to serving to guide itin its movement.

With the above and other objects in view the invention consists of acasing having an upper sash vertically movable therein and fitted withineach side of the casing, and partly overlapped by the upper sash is arotatable tubular guide-strip having a longitudinallyextending slotadapted to receive projections upon the lower sash in the casing.Transversely-extending slots are provided at points within the strip, soas to enable the lower sash to be forced into or out of position beneaththe upper sash. Means are also provided for simultaneously rotating thestrips, so as to cause them to assume a position over the inner faces ofthe sashes when closed, and thereby hold them against displacement andprevent the admission of air around the sashes.

The invention also consists of the further novel constructions andcombinations of parts hereinafter more fully described, and pointed outin the claims.

In the accompanying drawingsIhave shown the preferred form of myinvention.

In said drawings, Figure 1 is a view, partly in elevation and partly insection, of a window casing embodying my improvements. Fig. 2 is acentral vertical section therethrough. Fig. 3 is a section on line 3 3,Fig.

2. Fig. 1 is a sectionon line 4 1, Fig. 2. Fig. 5 is a central verticalsection through the casing and showing the lower sash raised. Fig. 6 isan enlarged section on line 6 6, Fig. 5. Fig. 7 is a detail perspectiveview of a portion of one of the guiding and lock strips, and

Fig. 8 is a perspective view of the strip-operating mechanism.

Referring to the figures by numerals of reference, 1 is a window-casinghaving parallel shafts 2 and 3, mounted in brackets 1, arranged withinthe top of the casing, and these shafts have drums 5 and 6 connected tothe ends thereof. A coiled spring 7 surrounds each shaft and is securedat opposite ends thereto and to its bracket 1, so that when the shaft isrotated in one direction the spring is tensioned. Each side of thewindow-casing is slotted longitudinally, as at 8, and extending througheach slot is an arm 9, projecting from one side of the upper window-sash10. A cord 11 connects each arm 9 with one of the drums 6, and saidcords are so wound upon the drum that when sash 10 is lowered and thecords 11 unwound the springs surrounding the shaft 3 will be tensioned.

Sash l0 normally contacts at its outer face with a stop-bead 12, securedwithin the cas ing, and the side edges of this sash overlap grooves 13,which are semicircular in crosssection and extend longitudinally withinthe sides of the casing. The sashlO does not eX- tend beyond thelongitudinal centers of the grooves, but is preferably in alinementtherewith. Arranged within each end of each groove 13 is a bearing-ring14, which receives a tubular stem 15. One of these stems is formed ateach end of a tubular semicylindrical guide-strip 16, which fits snuglywithin the groove 13 and is adapted to assume a position with its flatface alining with the window-casing. Each of the strips 16 has alongitudinally-extending slot 17 formed at the.

center of its flat face, and laterally-extending slots 18 communicatewith the slot 17. All of these slots 17 and 18 are of sufficient size topermit arms 19, which extend laterally from the lower sash 20, to traveltherein. Holding-lugs 21 also extend from the lower sash 20 and areadapted to travel within the slots 17 and 18, and the two slots 18 ofeach guidestrip are spaced apart a distance equal'to the distancebetween arms 19 and lugs 21. It will therefore be seen that when sash 20is in its lowest position its arms 19 and lugs 21 will rest within thetwo slots 18 of each strip 16. Sash-cords 22 are connected to the arms19 and extend through lugs 21 and then through the guide-strips 16 andtheir upper tubular extensions 15 to the drums 5. The springs of shaft2, to which drums 5 are secured, is under tension when sash 20 islowered.

Oppositely-arranged bell-crank levers 23 are secured to the lowerextensions 15, and the inwardly-extending arms of these levers areconnected by rods 24 with a lever 25, secured to a rotatable pin 26.This pin is supported within the sash 27 of the window-casing by abracket 28 and extends through the front of the sash and has a head 29whereby it may be either rotated or drawn longitudinally. The head hasan angular portion 30, which is normally seated in a correspondingsocket 31 in the sill. Springs 32 connect the other arms of levers 23with the window-casing.

A casing 33 is secured to the inner face of sash 20, near each sidethereof, and each casing contains a bell-crank lever 34:, to which isconnected an operating-rod 35, having a ring or other suitable device 36secured to it. Lever 34 engages and is adapted to operate aspring-pressed plunger 37, which is normally projected from the side ofthe casing 33 and is adapted when sash 20 is raised to engage any one ofthe series of ratchet-teeth 38, secured to the inner face of thewindow-casing.

When the sash 20 is in position beneath sash 10, its arms 19 and lugs 21rest within the slots 18, and the strips 16 are disposed with their fiatfaces contacting with the inner surface of sashes 10 and 20, as shown inFigs. 1, 2, 3, and 4. These strips are held normally in this position bythe springs 32, which are connected to bell-crank levers 23. They arealso locked by the angular portion 30 of head 29, which is seated insocket 31. When it is desired to raise the lower sash, the pin 26 isdrawn longitudinally, so as to release the angular portion 30 from itssocket, and said pin is then rotated, so as to operate the bell-cranklever 23 and extend springs 32. This operation will cause the strips 16to rotate in their grooves 13 until their flat faces register or alinewith the inner faces of the casing. Sash 20 is then drawn inward,causing its arms 19 and lugs 21 to slide in slots 18 until they assume aposition within the vertical slots 17. The tensioned spring connected todrums 5 will then cause said drums to rotate and will raise sash 20, sothat its arms 19 and lugs 21 will travel longitudinally within slots 17.By means of the plungers 37 and the ratchetteeth 38 sash 20 can belocked in any desired position. When it is desired to close the window,the sash 20 is drawn downward after being released from the ratchetteethand is then pressed outward in position under sash 10. Strips 16 aresubsequently automatically rotated by springs 32, so as to overlap theinner face of sash 10. They can then be locked by forcing the angularportion of head 29 into its socket 31.

It will be understood, of course, that the casing is groovedtransversely, so as to permit of the lateral movement of arms 19 andlugs 21 when the same are in slots 18. The

ably beveled, and the upper sash is provided with a shield or guard 39,which is adapted to overlap sash 20 when the window is closed andprevent air from entering between the two sashes.

It.will be seen that the strips 16 not only serve as guides for thelower sash, but also act as locks and weather-strips. With thisconstruction of window it is unnecessary to employ parting-strips and,moreover, it is absolutely impossible to open the window from theoutside.
